can't play gardening mama

Why I can't play it in my NDS? It says: "There's no save file" or so like that. But, when I check it, there is a save file. What should I do? :'(

Did you read Common Issues?

Yup,I have read it before, but I don't understand it. Sorry.....

Read the block of text under the 'save' issues. If there's something you don't get, specify it please.

Well, I've changed my mind, i found the latest software. Anyway, thx for your info!
